You conjure an anvil 500 feet above a point you can see. At initiative count 0 (Losing initiative ties) on the next round, the anvil hits the ground; creatures within 5 feet of the target point must make a Dexterity saving throw. On a success, they move to the closest unoccupied space outside of the radius, if no space is available or they cannot move, they automatically fail. On failure, they take 10d10 + 10 bludgeoning damage. Creatures within 20 feet of the target point take 4d4 thunder damage. If the path of the anvil (directly above the target point) is interrupted, the creature or object above it is hit first. If the creature or object is killed or destroyed, the anvil continues, though the damage dealt is subtracted from the final impact damage of the anvil. If the anvil deals less than 80 damage, the anvil survives the impact, and is an anvil of moderate quality.
